SANITARY HIGH CHAIR iaoaeao.

Specification of Letters Patent.

Application filed January 26, 1916. Serial No. 74,439.

To all whom it may concern:

Be it known that I, HORACE W. JENNER, a citizen of the United States of America, residing at Lawrenceville, in the county of Lawrence and State of Illinois, have invented certain new and useful Improve- .ments in Sanitary High Chairs, of which be readily and conveniently removed from" the supporting arms in order to allow the tray to be thoroughly cleaned or sterllized. With these and other objects in view this invention consists of certain novel combinations, constructions, and arrangements of parts as will be hereinafter fully described and claimed. l 1 1n the accompanying drawings: Figure 1 is a side elevation of the chair. Fig. 2 is a top plan view of the tray and a portion of the supporting arms therefor. 'Fig. 3 is a side elevation of the tray supported upon the supporting arms. Fig. 4 is a'section taken on the line H of Fig. 2.

view through one of the supporting arms, showing the retaining spring supported therein. Fig. 6 is a section taken on line 6-6 of Fig. 2. Fig. 7 is an enlarged horizontal section through a portion of one of the supporting arms for the tray, and showing the manner in which the tray and locking plate engage the supporting arms. Fig. 8 is a detail perspective of the tray detached from the supporting arms. Fig. 9 is a detail perspective of one of the pivoted ends of the supporting arms. Fig. 10 is a section taken on line 10-10 of Fig. 11 is a section taken on line l1-11,'of Fig. 1.

By referring to the drawings it will be seen that 1 designates the chair which may be formed of the usual construction, having the arm portions 2 secured thereto. Aplurality of tray supporting arms 3 are pivot-. ally connected to the upper ends of the arms 2 by having the flattened portions 4 connected to the arms 2 by means of the pivot pin-5. The arms 3 are so formed as to hang snugly in engagement with the arms Fig. 5 is a 2 of the chair and project upwardly in parallel relation relative to each other. The outer ends of the arms 3 are integrally connected by means of a transversely extending brace bar 4, as illustrated in Fig. 7 of the drawings. It, of course, should be understood that this brace bar 4 may be formed detachably from the arms 3, if so desired by being connected to the arms by means of elbows.

Each of the arms 3 is provided upon the inner face thereof with a longitudinally extending groove 5 formed therein. These grooves 5 carry the sliding locking bar 6 projecting into the arms 3, the grooves 5' constituting guiding means for the locking bar 6. I This locking bar 6 is provided with the finger hold 8 for permitting an operator to conveniently grip the finger hold and draw the locking bar 6 out of engagement with the tray 12, as will be hereinafter fully described. 1

A'coiled spring 10 is connected to each end of the locking bar 6, as illustrated in Figs. 5 and 7 of the drawings, and these coiled springs 10 fit within the arms 3 and have their inner ends secured to the side portions of the arms 3 by means of a rivet or other suitable securing means 11.

A detachable tray 12 which may be formed of porcelain or other suitable material is placed upon the arms 3 and is provided with the laterally extending flanges 13 which flanges project around the entire length of the tray 12. The flanges 13 over- Patented Dec. 26,1916.-

hang the side arms 3 as well as the transversely extending bar 4 thereof, constituting an eflicient support for the trap 12 upon the arms 3.

A retaining plate 14 which is substan tially concavo-convex in cross-section is secured to the front and rear face of the tray 12, as illustrated clearly in Fig. 4. These plates 14 may be secured and held in engagement with the tray 12 in any suitable or convenientmanner, such as being welded,

soldered, or in any other manner secured thereto.- It, of course, should be understood that these plates 14 if so desired may be formed integral with the tray 12.

From the foregoing description it will be seen that the locking bar 6 is adapted to reciprocate within the grooves or notches 5, and by drawing the locking bar 6 rearwardly to the position shown in Fig. 2 in dotted lines the-tray 12 may be readily removed from thesupporting arms 3 for the purpose of sterilizing or cleanmg the same.

It should be further understood that the tray 12 will be held in a rigid position against accidental displacement from' the arms 3 by means of the bar-6, and in view of the fact that the plates 14 are formed concavo-convex in crosssectioir the plate 14: upon the front of the tray 12 will snugly fit around the transversely extending bar 4 carried by the arms 3.

It should be understood that by placing a detachable tray upon a high chair, or the like, as illustrated and described, a very sanitary tray will be provided which may be emptied and thoroughly cleaned without interfering with the operation of the chair,

and also without the necessity of moving the entire chair to carry the tray to the sterilizing tank.

By carefully considering Figs. 1 and 11 it will be seen that a clasp 15 may be placed over the tray arm 3 and the chair arm 2 for firmly holding the tray against accidental upward swinging movement. The clasp 15 is provided with slightly outwardly turned ends 16, and this clasp 15 may be formed of spring metal so as. to permit the clasp to be readily placed in engagement with the chair and tray arms. It, of course should be understood that any number of these clasps may be used, as for instance, one clasp may be used upon each arm when so desired.

What is claimed is: 1. In a device of the class described, the

combination of a plurality of traysupporting arms, said arms being secured together at their'outer ends by means of a transversely extending bar, a tray supported upon said arms, said arms being circular in cross-section, a plurality of concavo-convex.

plates secured tosaid tray and fitting snugly around said arms for holding said tray against accidental removal from said arms, and a detachable locking means engaging said tray and'carried by said arms.

2. A device of the class described, comsignature.
